Book excerpt: Stratigraphic records in the Hudson Bay Lowlands (HBL), Canada, offer rare insight into local paleoenvironments and the Late Pleistocene climate system over North America. Age determinations on sub-till non-glacial materials suggest that the HBL, lying near the centre of the Last Glacial Maximum (LGM) extent of the Laurentide Ice Sheet (LIS), was ice-free for parts of Marine Isotope Stage 3 (MIS 3; 57,000 to 29,000 yr BP), MIS 5 (130,000 to 71,000 yr BP) and MIS 7 (243,000 to 190,000 yr BP). The MIS 3 age assignment is notable since it suggests the possibility of significant retreat of the LIS and a relatively high global sea level, both of which are a contrast to assumptions that North America was moderately glaciated, and that global sea level was relatively low during that time interval. Paleoecological proxies, including pollen and plant macrofossils, suggest that the HBL contained peatland and boreal vegetation during all previous non-glacial intervals, and pollen-based quantitative reconstructions of sites which are hypothesized to be MIS 3 and MIS 5a (~80,000 yr BP) in age suggest that climate during MIS 3 may have had less annual precipitation than during MIS 5a and present day. Stratigraphic analyses of these glacial and non-glacial sediments provide insight into the dynamicity of Late Pleistocene ice sheets; multiproxy analyses of three stratigraphic successions along the Albany River resulted in the recognition of at least three glacial advances from shifting ice centers within the QuĂŠbec sector of the Laurentide Ice Sheet during the Late Pleistocene. This dissertation contributes a chronological dataset for reconstructing the movement, timing and dynamics of Late Pleistocene ice sheets over North America, as well as paleoecological data for understanding the character and distribution of boreal peatlands during previous interstadial and interglacial periods.

This book was released on 1977 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quadra Sand is a late Pleistocene lithostratigraphic unit with widespread distribution in the Georgia Depression, British Columbia and Puget Lowland, Washington. The unit consists of horizontally and cross-stratified, well sorted sand, minor silt, and gravel. It is overlain by till and related glacial sediments deposited during the fraser Glaciation and is underlain by fluvial, estuarine, and marine sediments deposited during the preceding nonglacial interval.

Download or read book Late Pleistocene Archaeology and Ecology in the Far Northeast written by Claude Chapdelaine and published by Texas A&M University Press. This book was released on 2012-09-18 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Far Northeast, a peninsula incorporating the six New England states, New York east of the Hudson, Quebec south of the St. Lawrence River and Gulf of St. Lawrence, and the Maritime Provinces, provided the setting for a distinct chapter in the peopling of North America. Late Pleistocene Archaeology and Ecology in the Far Northeast focuses on the Clovis pioneers and their eastward migration into this region, inhospitable before 13,500 years ago, especially in its northern latitudes. Bringing together the last decade or so of research on the Paleoindian presence in the area, Claude Chapdelaine and the contributors to this volume discuss, among other topics, the style variations in the fluted points left behind by these migrating peoples, a broader disparity than previously thought. This book offers not only an opportunity to review new data and interpretations in most areas of the Far Northeast, including a first glimpse at the Cliche-Rancourt Site, the only known fluted point site in Quebec, but also permits these new findings to shape revised interpretations of old sites. The accumulation of research findings in the Far Northeast has been steady, and this timely book presents some of the most interesting results, offering fresh perspectives on the prehistory of this important region.
